Abstract: RCA 74,029 In a video disc player, the turntable spindle is held in engagement with the record center hole when the turntable is lowered to transfer the record to the receiver pads. A mechanism, responsive to the insertion of an empty jacket into the player, retracts the spindle to allow insertion of the jacket into the player free from interference with the spindle.

Abstract: RCA 74,077 CARRIAGE RESET APPARATUS FOR DISC RECORD PLAYER A record cover engages a carriage-mounted pushback member to effect translation of the carriage toward the carriage starting position during insertion of a cover into the player when the pushback member is latched. When the carriage arrives at the desired position, the pushback member is unlatched to allow it to rotate out of the jacket insertion path as the jacket is further inserted into the player.

Abstract: RCA 74,362 STYLUS CLEANING APPARATUS FOR VIDEO DISC PLAYER A stylus cleaner arm is pushed back to a retracted position when a record-bearing caddy is inserted into the player to load an enclosed record therein. The cleaner arm is held in the retracted position by the retained spine upon subsequent jacket withdrawal. The cleaner arm follows the caddy as it is withdrawn from the player until it engages a latch plate, which arrests the cleaner arm at an intermediate position. The stylus lifter gently drops a pickup stylus on the cleaner arm occupying the intermediate position as the caddy is further withdrawn from the player. The latch plate frees the cleaner arm to swing back to a standby position thereof during still further withdrawal of the caddy, thereby passing the cleaner arm underneath the stylus to wipe it clean. The stylus is raised away from the cleaner arm when the caddy is withdrawn from the player.

Abstract: RCA 74,078 A record side identification apparatus for a video disc player comprises a sensing member which is deflected to a first position and a second position in response to insertion of a video disc caddy into the player with a given side thereof respectively facing upward and downward. The deflected sensing member is depressed to illuminate the respective one of a pair of record side identification lights on the front instrument panel of the player during further insertion of the caddy into the player.

Abstract: RCA 74,557 A stylus arm carriage is driven across the record in synchronism with the radial motion of a pickup stylus by means of a carriage drive mechanism which includes a clutch. The clutch is selectively disabled to allow motion of the carriage without hindrance by the carriage drive mechanism.

Abstract: RCA 75,322 In a video disc player, the turntable spindle is held in a raised position such that it is maintained in engagement with the record center hole when the turntable is lowered to transfer a spinning record from the turntable to the receiver pads. A mechanism, responsive to the insertion of an empty jacket into the player, retracts the spindle to allow the insertion of the jacket into the player free from interference with the spindle.
